Delayed Massive-star Mechanical Feedback at Low Metallicity
The Astrophysical Journal, 2023 The classical model of massive-star mechanical feedback is based on effects at solar metallicity ( Z _⊙ ), yet feedback parameters are very different at low metallicity.

First Stellar Abundances in the Dwarf Irregular Galaxy Sextans A [PDF]
The Astronomical Journal, 2004 We present the abundance analyses of three isolated A-type supergiant stars in the dwarf irregular galaxy Sextans A from high-resolution spectra the UVES spectrograph at the VLT. Detailed model atmosphere analyses have been used to determine the stellar atmospheric parameters and the elemental abundances of the stars.

The Relationship Between Recent and Old Star Formation in Dwarf Irregular Galaxies [PDF]
Iranian Journal of Astronomy and AstrophysicsIn this paper, we investigate the structural properties of local dwarf irregular galaxies, including optical scale lengths, position angles, and star formation rates, using data from the LITTLE THINGS survey. Our analysis is based on a sample of 24 dwarf

MobiCOP: A Scalable and Reliable Mobile Code Offloading Solution
Wireless Communications and Mobile Computing, Volume 2018, Issue 1, 2018., 2018 Code offloading is a popular technique for extending the natural capabilities of mobile devices by migrating processor‐intensive tasks to resource‐rich surrogates. Despite multiple platforms for offloading being available in academia, these frameworks have yet to permeate the industry.

The inclination of the dwarf irregular galaxy Holmberg II
, 2014 We provide constraints on the inclination angle of the H\,{\sc i} disk of the dwarf irregular galaxy Holmberg II (Ho II) from stability analysis of the outer gaseous disk. We point out that a mean inclination angle of 27 degrees and thus a flat circular velocity of ~60 km/s, is required to have a level of gravitational stability similar to that found ...

Molecular Clouds in Dwarf Irregular Galaxies [PDF]
Highlights of Astronomy, 1989 The study of molecular clouds in dwarf galaxies was, until recently, an arduous task and provided detections in only a handful of sources (see Thronson and Bally 1986; Wiklind et al. 1986; Tacconi and Young 1987; Arnoult et al. 1988). Line strengths observed in CO were small (<100mK) and measurements were confined to one position per source, thus ...
